Hi,
I have a lot of huge tiff not-gereferenced raster.
These tiff are all with 4 bands (RGBA) and 10 pyramids inside.
I need to remove the piramids and retrieve a new tiff version without
the piramids and with only 3 bands (RGB).
Usually this work is do using imagemagick or vips, but I like to try to
use the gdal-translate to do this.
But Im not sure , because the tiff are not georef and also I'm not sure if
gdal is capable to read a 4 pyramid tiff and generate a 3 not-piramid tiff.
Andrea,
you can do it with gdal_translate and its creation options [1].
You can try with something like this:
gdal_translate -co COPY_SRC_OVERVIEWS=NO -co ALPHA=NO -co TFW=YES -co
PROFILE=BASELINE input.tif output.tif
Hope this helps.
Cheers,
Antonio
